The analysis of discharges with strong on- and off-axis ion cyclotron resonance heating shows that the transport of heat in JET is local and diffusive. Discharges with or without pellet injection are considered; in all cases, the electron temperature profile responds to the location of the heating. The total heat flow Q can be described by a local diffusive model of the form Q = -χ(qψ, |∇Te|) ne ∇Te, where χ is proportional to qψ1.75 and increases with |∇Te|. Several forms of the dependence of χ on |∇Te| are shown to give a reasonable fit to the data
